TRANSIT-CI-IUTE FOR $AFETY-PIN CARDING APPARATUS.

Specification of Letters Patent.

Application filed April 23, 1917. Serial No. 163,931.

1/ 0 all whom it may concern Be it known that 1, CHARLES B. GOLD- devices of that class available for effecting, I

successively and automatically,- the controlled transit of so-called safety-pins or the like, as from a charger or hopper to and for treatment, as by suitable carding mechanism, such devices being well desig nated transit-chutes for safety-pin carding apparatus.

The object of this invention is to provide a transit-chute of the character above indicated, which shall be capable of receiving, at its intake terminus, transmitting therefrom and delivering at its discharge terminus, all automatically and in rapid succession, pointed fasteners of that type, commonly known as safety-pins, each thereott being caused, automatically and during its sliding passage downwardly along the 1nterior of said transit-chute, to assume a predetermined posltion and accordingly arrive at the discharge terminus of such transitchute in readiness for delivery therefrom; which shall be simple and inexpensive as regards, its construction; durable, efficient and reliable in practical service; and which shall possess certain Well-defined advantages over prior analogous devices.

This invention consists incertain combinations, details and parts, together with the novel disposition and relative arrangement of said parts whereby the attainment of the foregoing object is renderedpracticable, all of which will be hereinafter more specifically referred to and setforth in the claims hereto appended.

T he invention is clearly illustrated in the accompanying drawing, wherein:

Fig. 3 is a cross-section of same, as along the dotted line y-@ of Fig. 2.

Fig. & is a detail cross-section as along the dotted line ze of Fig.1.,

Fig. 5 is a View showing in perspective and detached the end-for-end pinreverser which I purpose making use of. i

' Fig. 6 is a view similarto Fi 5, showing the point-down pin adjuster which I purpose making use of.

Fig. 7 is a diagrammatic plan view,shoW- ing more clearly the end'for-end reversing features'oi my improved transit-chute, and the relatlon thereto of a safety-pin undergoing treatment and advancing within'said' transit-chute coiled end foremost. Fig. 8 is a view similar to Fi 7 the pin there illustrated being shown as advancing capped end foremost.

Fig. 9 is a detail sectional view showing in a general way the inclination of my improved transit-chute, and more clearly the end-for end action of certain of the pins undergoing treatment therein.

-Having reference to the accompanying drawing, wherein similar reference-numerals denote like parts throughout the several views, I, in carrying out my invention, provide a chute-like structure which consists "of an elongated base 2, flanked at its Opposite sides by upstanding side-members 2 2", said structure being disposed at a suitable inclination in'practice and serving to,

receive,it'or a sliding movement downwardly therealong andin rapid succession, so-called safety-pins, each of which assumes, on entering said chute, a fiatwise position on, and moves correspondingly and endwise, by its own gravity, downwardly along the base.

aforenamed.

Each of the safety-pins for the handling of which my improved chute is more particularly adapted, is formed from wire, affords the usual cap or shield and a coil at its opposite ends, and may enter my improved chute coil-end or shield-end first, its flatwise position relative to the base 2 being in all instances immaterial; that is, whether its position onsaid base be such that one or the other of its generally fiat faces is uppermost.

It is important, however, that each safetypin fed into my improved chute shall arrive at the discharge terminus thereof shield end on and pin-point down. Hence, it is ne-edtul that the safety-pin, when fed into my improved chute coil-end first, shall be automatically reversed end fof-end'at some Patented Apr. c.1920.

as defined by the b I effect reversal end for end of each pin or the like fed into my improved chute coilend first by depressing the level of the base 2 at a point suitably removed from the in take end of said chute, and positioning on said base at the said depressed level thereor,

an end-for-end pin reverser, the same consisting in this instance, of an elongated body 3 afiording an upstanding, take-off enlargement 3, the posterior face of said enlargement being suitably curved downwardly and rearwardly, while its advance face is inclined downwardly and forwardly with more or less regularity.

lit the leading-off end of the base 2 of the next higher level thereof, and in line with the course of movement of tee safety-pin or the like within my improved chute and undergoing treatment, there is disposed a pinreleasing tongue 3, arranged in unison with the base level lying next rearwardly thereof, suitably overlying the pin reverser aforenamed, and being provided at its free or advance end with a recess l curved or bowed inwardly in approximate conformity with an arc of the outer circumference of the coil of the pin or the like undergoing treatment, the width of the tongue aforenamed being less than the width of the base 2, to the end that said tongue may be flanked at its opposite sides by open, elongated spaces l, 4%, and the purpose of which spaces will shortly'bc made apparent.

In practice, each traversing flatwise and endwise its cour e of sliding movement o 2, makes escape and descends, flatwise and endwise, from the advance end of the tongue 3" upon arriving fairly thereat; does this somewhat more abruptly when its advancing end is its coiled end than when its advancing end is its capped or shield-carrying end; and is facilitated in its escape and descent from the tongue aforenamed by the presence of the spaces a at", whereby due clearance is provided. for the usual opposite, elongated members of the fiatwise-moving pin, all as will be readily understood.

It will be seen in this connection that the recess 4, generally contoured as hereinbefore mentioned, provides clearance for an arc, and essentially the rear arc, of each pin. advancing coiled end foremost, whereby the coiled end of such pin. is allowed to dropfrom the tongue 3 at a given point of time;

and since no similar clearance is provided for the cap or shield, or any segment thereof, of any pin advancing capped or shieldcarrying end foremost, the cap or shield of each pin thus advancing serves, accordingly,

to prolong somewhat the stay or occupancy the pin on the tongue aforenamed relative to the point of time aforenamed at which 7 the enlargement 8, and momentarily engage V it ie same'at its distant face, substantially as indicated in full lines inl ig. 2 of the drawing, whereby said pin is permitted to pass onward downwardly along the base 2, without any end-for-end reversing action having been imparted thereto, and arrive at the discharge terminus of my improved chute.

capped or shield-carrying end foremost, all as required in the practical operation of said chute. On the other hand, the stay on said tongue of each pin ad ancing coiled end foremost is cut short as before explained sufficiently to cause the advance, coiled end of such pin, in advancing and descending from the tongue aforenamed, to fall somewhat short of the enlargement 3, and momentarily engage the same at its downwardly and rear- ,wardly inclined face, aforenamed, andslide downwardly and rearwardly more or less on such face, substantially as indicated in dotted lines in Fig. 2, whereby, aided by the momentun'i of the moving pin, a somersault or end-for-end reversing action is automatically imparted to the pin, thus substituting, end on, its capped or shield-carrying end for .its coiled end, under which conditions the pin continues its sliding action downwardly along the base 2, and arrives at the discharge terminus of my improved chute capped or shield-carrying end foremost, all as required in the practical operation of said chute.

It may be here pointed out that, in a gen eral sense, the tongue aforenamed andthe pinreverser aforenamed, the latter positioned below and suitably in advance of the delivery end of the former, constitute the means wiereby each pin fed into my improved chute and permitted to slide down wardly along its base, is caused to automatically undergo, contingentlyas to whether it moves along said base coiled end or shieldcarrying and foremost, an endfor-end reversing action, and in such a manner aste always arrive at the discharge end of my improved chute capped or shield-carrying end foremost.

It is further important that each pin traversing my improved chute shall always arrive at its discharge terminus, not only capped end foremost, but pin-point down; that is, that the pin shall have shifted itself automatically from its generally flat position to a position more or less upright or perpendicular to the base of the chute, and with its pin-point lowermost.

For the attainment of the foregoing end I again depress the base 2, at a point therealong suitably in advance of the end-for-end reverser aforenamed, and position on the base, so further depressed, a point-down pin adjuster, the same consisting inthis instance, of an elongated body 5', suitably out under at its opposite sides and lengthwise thereof to form therefor opposite, lateral webs 5 5", the free edge of each of which, and more essentially the forward portion thereof, is irregularly curved outwardly and downwardly with respect to said body, or in conformity with the segment of a heli- Vcodial curve, the width of said pin adjuster, inclusive of its opposite webs 5 5", being somewhat less than the distance intervening directly between the side-members 2 2, whereby open, elongated spaces 6 6, analogous to 4 4 are provided at the opposite sides of the body 5 and each in parallelism therewith. The function of each of the spaces 6 6" will shortly be more fully explained.

1 position onthe base 2, more or less immediately in advance of the pin adjuster just described, a central, upstanding parting fin 6, which serves to form di- -visional channelsections 7' 7", at the opposite'si'des of said fin, each of which channels is materially reduced widthwise in comparison with the width of the general channel of the device, as formed by the base 2 in conjunction with the opposite side-members 2 2", said channels also being, each in direct communication with the elongated space 6' or 6" which immediately precedes it and each of which leads to and communicates, at a point somewhat in advance of the fin 6, with the final section of my improved chute, the passage forming channel of which is also reduced widthwise sufiiciently to prevent any pin gaining, entrance thereto and which shall have been acted upon, as to be hereinafter explained, by the pin adjuster of my improved device, from-returning in any undue measure to its previous flatwise position relative to the base 2, such final section of my improved chute being denoted by the refer- ,ence numeral 7.

In practice, as the pin, lyingflatwise and cappedend on, arrives, in its movement the pin adjuster web now actingthereon, I

sufliciently on its own longitudinalaxis and in'such a manner as to cause 'thesameito drop with its pin-point lowermost into one or the other of the spaces 6 6", and accordingly reach, by way of one or the other of the divisional channels 7 7", for further movement therealong and in a suitably upright position, the final terminal section of the device, said pin accordingly arriving ultimately at the discharge terminal of the device, in said suitably upright position, with its capped-end on and pin-point down, all in readiness for delivery from the chute, as to any appropriate mechanism, such as, a carding machine, provided for further treatment thereof, the wing-like portion aforenamed being always positioned relative to the pin for the attainment of the foregoing end, through cooperation thereof, as above defined, with one or the 5 5".

It will be understood-that the entrance of the pin into either of the openings 6'6, with its attendant uprightin'g action, and the passage thereof through that one of the divisional channels 7' 7 communicating with such opening, is dependent upon-the fiatwise position of the pin when it reaches the pin adjuster aforenamed; that is,

other of the webs whether one or the other of the generally flat faces of the'pin is lowermost: said pin entering, however, and moving onward from'one or the other of the openings 6 6" irrespective of what its fiatwise position maybe when it reaches the pin adjuster.

It will be further noted that. the pin,

while being acted upon by the pin adjuster as hereinbefore explained, and by reason of the helicoidal form of each of the webs of said adjuster, is diverted somewhat laterally from its otherwise straight course o'f'movement; and to compensate for. this, each of theychannel-sections 7 7 may be suitably, widened or flared at its intake end, substan tially as indicated inthe' drawing.

It is further desirable that means be provided for duly controllingthe movement, in succession and in advance of the tongue 3, of the pins which may be fed, one by one, into my improved transit-chute; and in this connection; I provide a shaft 8, mounted to rotate in suitable bearings, as 8" 8", and arranged in due connection with any able pulley 9 firmly mounted on said shaft. There is also firmly mounted onshaft 8. a

controller 9, here shown in the form of a wheel, faced peripherally with a suitable yielding material, as rubber, leather, or the like, and dipping at its lower marginal segment somewhat into the course of movement of any pin or pins traversing my improved chute that is, the clearance between the lowermost peripheral point of the controller 9 and the base 2 thereunder, is such that no pin, whether fed into the chute capped end or coiled end first, can pass the controller 9' except when, and proportionally to the rate of speed at which, such controller may be duly rotated, all as will be clearly understood on reference being made to Fig. 2 of the drawing.

Hence, the rotation speed of the controller 9 being, in practice, properly regulated, collision of any on-coming pm with any pm leaving the tongue 3 is avoided, as will be readily noted, the movement of such oncoming pin being properly retarded to this end by the controller 9.

To prevent any on-coming pin from riding upon or'nosing beneath any pin on which the controller 9 may, at any time, be acting, the intake section of my improved chute may be provided, if found advisable, with a suitable cover or bridge, as 9"; and

analogous bridge-members, may, if found advisable for preventing any casual displacement of any pin or pins from the chute, be employed at the intake ends of the channel-sections 7, 7", or line of movement deflection, hereinbefore referred to, of each pin as it traverses myvimproved chutej .It will be seen that my improved transitchute is particularly well adapted for the purposes for which it is intended, and further that the same may be modified to a considerable extent without material departure from the spirit and principle of my invention, as set forth in the claims hereto appended.

I claim:

1. A chute for the transit, successively next preceding section thereof; an end-forv end pin reverser on the base-section of the lower level; and a pin-releasing tongue, at the delivery end of the base-section of the higher level, said tongue suitably overlying said reverser.

safety-pins or the like, consisting of a channel-forming structure, one. section of the base of which is depressed relatively to the next preceding section thereof; an end-forend-pin reverser on the base-section of the lower level; and a pin-releasing tongue at the delivery end ofthe base-section of the higher level, said tongue provided with an inwardly curved recess at its advance end, and suitably overlying saidrcverser.

3. A. chute for the transit, successively and each solely by its own gravity, of siifety pins or the like, consisting of a channel-forming structure; a controller, comprising a' rotatable shaft having a wheel mounted thereon, said wheel peripherally faced with a yielding material, dipping suitably into the channel aforenamed, and adapted, when duly rotated, to engage and retard the movement ofeach pin arriving thereat relatively to the movement of the pin moving next in advance thereof; and means for duly rotating said controller.

4%. A chute for the transit, successively and each solely by its own gravity of safety-pins or the like, consisting of a channel-forming structure; a controller adapted to retard the movement of each pin arriving thereat relatively to the pin moving next in advance thereof; and means, situated beyond said controller for contingently effecting the reversal, end for end, and automati- V cally, of more or less of the pins arriving at upstanding, take-off enlargement, suitably spaced forwardly away from the free end of the tongue aforenamed.

6. A chute for the transit, fiatwise, successively and each solely by its own gravity, of safety-pins or the like, consisting of a channel-forming structure, and affording at one point therealong a rotatable medium for automatically retarding the movement of each pin arriving thereat, relatively to the movement of the pin moving next in advance thereof; at another point therealong, a device for automatically reversing, end for end, more or less of the pins arriving thereat; and at a point still farther therealong, means for automatically shifting each pin arriving thereat from its fiatwise position into a position suitably up right, with its pinpoint lowermost.
